Scientific paper

In the course of our Galactic plane radio survey, we have discovered an outstanding young pulsar candidate: a steep-spectrum radio shell 4' in diameter surrounding a flat-spectrum radio core which is, in turn, coincident with a bright X-ray source with a power-law spectrum. Assuming a distance of 8 kpc consistent with the highly absorbed X-ray spectrum, the intrinsic PWN luminosity of 2 e35 erg/s would place this source among the top five E dot pulsars in the Galaxy. We propose to observe the object with Chandra in order to a) resolve the pulsar from its surrounding PWN and measure its X-ray flux and spectrum, b) study the structure of the PWN, and c) detect the thermal emission of the remnant shell.
